lMFROVEME'NT IN TILE-MACHINES.

The Schedule referred tovin these' Letters Patent 'and making part of the seme.

I, ALBERT MOORHOUS, of Indianapolis, in the county of Marion and State of Indiana, have invented-certain Improvements in Tle-lVIachines, of which the following is a specification.

Nature mcl Objects of thcliwent'ion.

The' object of lny invention is to provide for public use an improvementV in tile-machines, whereby they shallbe adapted toscreen the clay passing through them of gravel, stones, 85e., in a convenient andcx pcditious manner; 'and to this end,

The -nvention consists in arranging screens and dies in connection with hinged doors, which close the ends of the plunger-box, as and for the purpose specied.

Description of. the Accompanying Drawing.

Figure l is a side elevation of a -tile-machine cmbodying my invention.

Ficure2 is a horizontal orl )lan view of the cut-oi' and plunger-chambers, had hy removing the upper plate and under drum.

Figure 3 is a vertical longitudinal section of the lower part of the mud-drum andthe npper'part of the plunger-chamber, to show moreclearly the con-- struction aldarrangement of the cut-oli' and cam for 'operating the VVsame. l l Figure. 4 is an elevation of the shutters closing the' General Description.

C, vertical shaft D, dies E, and cut-cti1 F do not dii'er materially from tile-machines as ordinarily constructed, and as no claim `is made to any part, except as herein clcarlypointed out, it is not deemed necessary to do more than name by letter these several parts oi' the machine.v y Y In order to provide a more vconveneutf'a'ml efficient means of clearing the lp'lnnger-chambers of gravel or other foreign matters that may find their way therein by being lnixedavith the clay, and at the same time provide the requislite means oi screening the clay before it passes to-the dies E, I arrange the latter in hinged shutters G, which constitute the ends of the plunger-chambers B, and. attach the screen H on the' inside of the shutter in such a manner that when it becomes necessary to clean the screen from gravel, Sto., that may have lodged against it, all that is required is to openthe shutter, when the gravelor other obstruction may bev readily removed; and by this means the interior of the chamber is also accessible;

The screen H is placed about six inches inthe rear of the die so as to afford lample space for the clay to form int-o a compact niass before it passes into the die. v

The shutters arc-secured, when cl0sed by meansof T-'boli-s.

The screens are provided with slots in their top and Ybot-tom flanges, through which project pins that `are set in the door.'

Y creased.

W'hen the shutters have been opened, to remove any gravel' that may' have lodged against the screen ,and it is not necessary .to remove the clay from tho chamber, it will be found that the shutters will be dicult to closeon account of the compactnessV oi the clay, and in order to force the shutter back to its position I provide a chain attached by' both its ends to the side of thechambcr through which to pass a lever with which to pry the shutter back to its place.

v The mud-drum is constructed with a recess iu the# center of-the bottom by making the outer part oi' the bottom aring, J, and covering the center opening with a plate, K, which gives space for acam oEjgreaterstrength, and also affords lroom for upward-projecting lugs o, attached to the cut-oli' with O.'
